Created attachment 502114 [details] smoltSendProfile -p Description of problem: After upgrading F14 -> F15 the system fans now stay fixed at the same modest speed. CPU frequency scaling works fine, but as temperature rises with higher loads, a cap is imposed (by BIOS?) at the maximum frequency as reported by 'cpupower frequency-info'. Version-Release number of selected component (if applicable): 2.6.38.6-27.fc15.x86_64 Steps to Reproduce: 1. Run CPU intensive jobs for a couple of minutes (a few big Java builds in my case) Actual results: Fans stay at same speed, CPU temperature rises, max frequency is throttled back to 800MHz Expected results: Fan speed should increase. Additional info: Can this have any relation to display configuration? I have a hard time reproducing this at home with the laptop on its own, whereas it hits consistently at the workplace with an external monitor attached (hence a higher load at the graphics)
Could this in fact be a problem with the proprietary nvidia driver (270.41.06) not controlling the (GeForce 8400M GS) GPU fan correctly?
cpupower would usually report "[...] frequency should be within 800 MHz and 2.50 GHz", but when this happens, it reports: [root@jerry ~]# cpupower frequency-info analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 1 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us. hardware limits: 800 MHz - 2.50 GHz available frequency steps: 2.50 GHz, 2.50 GHz, 2.00 GHz, 1.60 GHz, 1.20 GHz, 800 MHz available cpufreq governors: ondemand, userspace, performance current policy: frequency should be within 800 MHz and 800 MHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 800 MHz (asserted by call to hardware). boost state support: Supported: no Active: no
Can you try it without the nvidia driver?
I suppose I could, but the problem appears to have 'dried up' in between, as I am no longer able to reproduce it with the current kernel (2.6.38.8-32.fc15.x86_64) and corresponding nvidia driver (275.09.07). So probably NOTABUG any more.
